So take it from me, when the recipe says to go slow and literally add the oil drop by drop, it truly means literally. It isn't to say that it takes very long to make mayo (unless you have to start all over again). It actually doesn't take long at all. You just need to do it right. Drop by drop.
Also, I tried it in my food processor which has a gracious 14-cup capacity (love that thing), but it didn't work for this because it was just too big. I switched over to my handy stick blender, and finally things started happening. So if you have a large food processor, use the small bowl attachment, or try another mixing method.
Homemade Mayonnaise
- 1 large egg yolk, at room temperature
- 2 tsp white wine vinegar
- 1/4 tsp Dijon mustard
Put the yolk, vinegar, and the mustard in a bowl, blender, or food processor. Whisk or whir to blend. Drop by drop (literally!! don't go to fast here...) start adding the oil, mixing all the while. When you've got about 1/4 cup oil beaten in and the mix is starting to look like mayonnaise (around 4 minutes or so), you can add the remaining oil more steadily, but still slowly. Use at least 1/2 cup oil, and up to about 1 cup to get the consistency you want. We only used the minimum 1/2 cup oil, and we liked how thick and flavorful the result was.
- 1/2-1 cup oil, mild (such as grapeseed or canola) or more flavorful (we used olive), or a combination
